DJ and owner of the newly-reopened vinyl store ZudRangMa, Maft Sai tells us about his shop and gives us some advice about collecting vintage records.

How did ZudRangMa begin?
From my own record collection. When I moved back to Thailand, I had a lot of records and never stopped looking for new ones. I had more than one copy of some, so I thought about having a shop where I could trade with other collectors.

What kind of music do you sell?
Most of it is world music—Jamaican, African, molam, look thung, funk, soul, reggae and many rare grooves that come from the same root.

Where did you find these records?
I find record shops and learn what they have, what their highlights are and what are not. Then I choose the ones that are not highlights and get a cheap price. I keep doing this everywhere I travel.

Who are your customers?
There is a wide range of customers, actually. Most of them are foreign collectors, though—not many Thais.

Can you give us tips about buying the right records?
Buying a record in the shop is different from downloading from the internet, where you can listen to it first and then decide whether to buy it or not. At a record shop, even if you can test that the record works, you have to buy it right away, or else it’ll be gone by the time you come back.
